1. Open the cap on the expansion tank and release the pressure.


2. Raise the car.

3. Remove the lower front cover.

4. Drain off the coolant.

5. Lower the car to the floor.


6. Unplug the mass air flow sensor connector.

7. Remove the air hose and mass air flow sensor.

8. Release the tension of the poly-V-belt using 83 95 254 Drawbar handle, hydraulic belt tensioner .


9. Remove the belt from the power steering pump and water pump.
